I am having the exact same problem. The Sales Tax Center used to show all tax agencies and all months under Sales Tax Owed. Now, because I have not had any sales tax liability so far this year, nothing shows there for "current year." The only "agency" listed is "Original Sales Tax" and the "Record Tax Payment" option is grayed out. If I select "previous year" I can see my tax agency and all months, even months with no tax liability. This is a problem because I need to enter a late filing fee. I've never had an issue with this until this year. I could always select the agency, select the month, and enter an adjustment for late fees.
